Multicore processors have become ubiquitous across many domains, such as datacenters and Smartphone's. As the number of processing elements increases within these processors, so does the pressure to share the critical on-chip cache resources, but this must be done energy-efficiently and without sacrificing resource guarantees. The authors propose a scalable dynamic cache-partitioning scheme, DR-SNUCA, which provides an energy-efficient way to reduce resource interference over caches shared among many processing elements. Their results show that DR-SNUCA reduces system energy consumption by 16.3% compared to associatively partitioned caches, such as DNUCA.
